FEED SPOUT FOB, DISK CRUSHERS.

Application led November My invention relates to feeding means for' disk Crushers and particularly to a feeding spout adapted to feed the material to be crushed to the crushing space defined by a pair of opposed crushing disks. It has for one purpose to provide a spout of the type shown adapted to feed material to the space between a pair of opposed concave disks, the spout i penetrating one of said disks. Another object is the provision of a removable and reversible lining for such a spout. Another object is the provision of a removable discharge lip for such a spout. Other objects will appear from time to time in the course of thevspecification and claims. I il lustrate my invention more or less diagranr matically in the accompanying drawings whereinv Figure l is a vertical longitudinal section along the axis of rotation of the disks;

Figure 2 is a section on the line 2-2 of Figure l; and

Figure 3 is a section on the line 3 3 of Figure l.

Like parts are indicated by like symbols throughout the specification and drawings. A is any suitable crusher supporting member positioned on a base A1 and adapted to support a bearing fragmentarily shown as A2 in Figure l. Rotatingin such bearing is the hollow shaft B terminating in an outwardly flared cup portion B1 with an interior spherical surface B2, terminating in an outwardly projecting circumferential flange B3.

C is a solid shaft adapted to rotate within the hollow of the shaft B, the axes of the two shafts being` slightly inclined to each other. C1 is a spherical surfaced head at the end thereof adapted to conform to the opposed spherical surface B2 which it engaged by means of a babbitt bearing mem ber C2.

D is a centrally apertured'carrying plate having a circumferential rearwardly posi tioned flange D1 adapted to be secured to the circumferential flange B3 of the hollow shaft B, for example by means of the bolts D2, nuts D3, and spacers D4.

E and E1 are opposed concave disks mounted one on the member C1 and the other on the member D, and adapted to define a lenticular crushing space. The means 13, 1925. Serial N0. 68,746.

of attachingl these disks forms no part of the present invention and are not described in detail. The disk E1 is centrally aperturedas at E2.

G is a feed spout supported on any suitable frame work, for example by the supports G1. It terminates just short of the disk E1 and is provided with a removable lip G2., of any suitable refractory material, for example manganese steel. The lip is provided with the rearwardly projecting arms G3 adapted to seat in the depression G4 in the sides of the chute G. The arms terminate in outwardly flanged lips G5 perforated at G'3 to admit the passage of a securing bolt G7 the opposite end of which passes through the outwardly Yprojectingears G8.

I H is a removable linerV for the chute, preferably constructed of manganese steel or some other suitable refractory material. It inclures a thicker central portion H1 with the thinner side portions H2 projecting upwardly from it and conforming to the interior of the chute. is a lug positioned intermediate the ends of the member H and apertured as at H4 to receive a securing pin H5. It will be understood that the lug passes through an aperture Hf in the botn tom of the chute. position of the lug andthe location of the aperture are such that the liner may be reversed to position its upper end, when worn, at the bottom ofthe chute.

The use and operation of my invention are as follows:

My spoutis adapted for employment with a crusher in which a` pair of opposed disks are rotated in unison about a generally hori- The size of the liner, the l zontal axis, the axes of the two disks being slightly inclined in lsuch fashion as to vary the clearance or the distance separating corresponding points upon the two disks as the disks rotate. On of the disks is mounted on a centrally apertured holder and is itself centrally apertured to permit the penetration of the discharge end or lip of the spout. charged into the upper end of the spout, passes downwardly by gravity through the spout, passes over the lipl and into the lenticular space defined by the opposed concave disks. rlhe two major points of wear on The material to be crushed is disthe'spout are the lip and the bottom of the upper end of the spout. Vhen the Crusher is operated under forced'feed and the spout is filled with material and material is heaped up above the top of the spout the bottom of the spout is protected from the shock or abrasion of fragments dropped from above by the fragments already resting upon the spout bottom and moving downwardly therealong as the material undergoing crushing is discharged from the crushing zone. At such time, however, the crushing zone being substantially filled with fragments undergoing reduction, there is a very heavy wear about the edge or lip of the discharge end-of the chute. lVhen the erusher is operating under light feed, on the contrary, the crushing zone is relatively sparsely occupied with material undergoing crushing and the wear against the edge or lip of the inner edge of the spout is much lighter. However the fragments of material falling from above upon the bottom of the upper or outer end of the spout tends to abrade or wear away the bottom of the spout.

I provide a spout in which these heavy wear taking areas are protected by removable members which may be replaced when worn, without necessitating replacement of the entire casting. In order to protect the discharge edge or lip of the spout I provide a removable rim or ring, preferably of manganese steel `or someother refractory orrwear resisting material. This ring is provided with two arms which seat in slots or notches in the sides of the discharge spout and terminate in outwardly turned flanges apertured in line with flanges or ears on the supporting' frame work or base of the Crusher. Securing bolts pass through the apertures and are tightened down with nuts to draw the rim. or ring iirmly against the end of the spout. Preferably the interior of the spout increases in diameter toward the crushing zone, the edge furthest from the crushing zone being of somewhat greater thickness than the spout wall.

In order to protect the bottom of the spout I provide a removable and reversible liner which increases in thickness from the edges toward the middle. The center of the bottom of the liner is provided with an apertured lug` adapted to pass through a slot in the bottom of the spout. Wlhen so positioned a bolt or other fastening means may be passed through it, holding it firmly iii-place. The thickness of the liner is preferably such as to raise its bottom somewhat above the inner edge of the ring or lip, as shown in Figure l. Thus the liner cannot be so far worn down as to be below the inner edge of the ring. The liner being identical at each end and its lug being equidistant from the ends, it may be reversed.

This is particularly important since the wear upon the liner is normally far more rapid at t-he upper than at the lower end.

It will be realized that whereas I have illustrated an apparatus particularly adapted for my purpose that nevertheless I do not wish to be limited to the specific description and showing herein. Many changes might be made in size, shape, number and disposition of parts without departing from the spirit of my invention and I therefore wish my disclosure to be taken as in a broad sense illustrative or diagrammatic.

I claim:
